Happy to help with motivation. The original intent is to have a minimized
reproducer of an issue as a part of the test suite. The point of the test case
is to feed SPIR-V Backend with LLVM IR without saturation arithmetic intrinsics
and ensure that SPIR-V Backend is able to deal with those intrinsics appearing
along the way in translation. There is a separate test case in the test suite
for the same intrinsics explicitly represented in the input LLVM IR, and it's
another case, different from this one.
